[0179] Preparation of polymer compound (B)

[0180] According to the present invention, above-mentioned polymer can be prepared according to the method comprising the following steps:

[0181] (a) providing a monomer composition as described above; and

[0182] (b) initiating free radical polymerization in the monomer composition.

[0183] Standard free-radical polymerization is described in detail in Ullmann's Encyclopedia of Industrial Chemistry, Sixth Edition, among others. In general, polymerization initiators and optionally chain transfer agents are used for this purpose.

[0184] The polymerization can be carried out under standard pressure, reduced pressure or elevated pressure. The polymerization temperature is also not critical. Generally, however, it is in the range of -20 to 200°C, preferably 50 to 150°C and more preferably 80 to 130°C.

[0185] Polymerization step (b) can be carried out with or without dilution in oil. If diluted, the amount of the monomer ...

Embodiment approach

[0198] According to a preferred embodiment of the present invention, said polymer-inorganic nanoparticle composition is obtainable by grinding a mixture comprising one or more intercalation compounds (A) and one or more polymer compounds (B),

[0199] Wherein the intercalation compound (A) is a nanostructured compound comprising a multilayer fullerene-like nanostructure consisting of metal chalcogenides each having the molecular formula MX 2 A multilayer composition of (M=W and X=S), which preferably has a spherical shape,

[0200] Wherein said one or more polymer compounds (B) can be obtained by polymerizing the following monomer composition comprising:

[0201] a) 1 to 60% by weight, preferably 2 to 50% by weight, more preferably 2 to 40% by weight, most preferably 3 to 35% by weight of said one or more polymer compounds (B) or multiple functional monomers as component a); and

[0202] b) 10 to 99% by weight, preferably 20 to 98% by weight, more preferably 30 to 98% by we...

Abstract

The invention relates to polymeric-inorganic nanoparticle compositions and preparation processes thereof. The invention also relates to an additive and lubricant compositions comprising these polymeric-inorganic nanoparticle compositions, as well as to the use of these polymeric-inorganic nanoparticle compositions in an oil lubricant formulation to improve tribological performance, in particular to improve extreme pressure performance and friction reduction on metal parts.

Description

technical field [0001] The invention relates to a polymer-inorganic nanoparticle composition and a preparation method thereof. The present invention also relates to additives and lubricant compositions comprising these polymer-inorganic nanoparticle compositions, and to the use of these polymer-inorganic nanoparticle compositions in oil lubricant formulations for improving tribological properties, in particular It is used to improve the extreme pressure performance and friction reduction rate on metal parts. Background technique [0002] The invention relates to the field of lubrication. Lubricants are compositions that reduce friction between surfaces. In addition to allowing freedom of movement between two surfaces and reducing mechanical wear of the surfaces, lubricants can also inhibit corrosion of the surfaces and / or can inhibit damage to the surfaces due to heat or oxidation. Examples of lubricant compositions include, but are not limited to, engine oils, transmissi...
